1'0 0, whom, it may concern;

Be it known thatwe, THOMAS C. BELDING and CHARLES H. SOHLABACH, citizensof the United States, residing at Canton, in the county of Stark andState of Ohio, have invented certain new and useful Improvements inHot-Air and Ventilating Registers; and we do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the figures of reference marked thereon, in which Figure l is across-section through line was, Fig. 2.

The present invention has relation to hotair and ventilating registers;and it consists in the different parts and combination of partshereinafter described, and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, 1 represents the register face or plate,which is formed of a size to correspond with the size of theregister-box, reference being had to the ordinary overlapping flanges orportions, which of course rest upon the floor or other structure towhich the register proper is to be attached or connected. The register-plate is of course formed with openings, which openings may be of anydesired design, reference being had to allowing the heated or other airto freely escape through said plate.

The register box or frame proper consists of the side members 2 and 3and the end members 4:, which when connected together produce arectangular frame. The side members 2 and 3 are each provided with theend flanges 5, which flanges are for the purpose of providing means forconnecting the end members 4: with the side members 2 and 3; but it willbe understood that flanges, such as 5, may be formed upon the endmembers 4, and thereby accomplish the same object, it of course beingunderstood that if in the event flanges, such as 5, are formed upon theend members no flanges are to be formed upon the side members 2 and 3.

For the purpose of securely connecting the side members and end memberstogether rivets or their equivalents 6 are to be employed.

Each of the side members 2 and 3 are provided with the projectingflanges 7, which flanges are for the purpose of adding strength andrigidity to the upper part of said side members and also form a rest forthe registerplate 1.

The end members 4- are substantially of the form shown in the drawings,and, as shown, their top or upper edges are provided with the flanges 8,which flanges are formed by first folding a portion of the end membersover and upon itself and then folding the double portion at an angle tothe end members. The lower edge of the end members 4 are provided withthe U-shaped portions 9, which U shaped portions are formed by bendingthe lower portions of the end members as illustrated in Fig. 4., therebyforming grooves 10 for the purpose hereinafter described.

The blade or valve carriers 11 and 12 are located upon the inner facesof the end members 4, their upper edges being provided with the flanges13, which flanges are for the purpose of overlapping the flanges b,formed upon the end members 4:. The lower portions of the blade or valvecarriers ll and 12 are provided with the ribs 14, which ribs areprovided with the apertures 15, said apertures being for the purpose ofreceiving the trunnions 16 and 16.

Below the ribs 14 are located or formed the flanges 17, said flangesbeing for the purpose of holding the bottom or lower portions of theblade or valve carriers in a fixed position by seating the flanges 17into the grooves or recesses 10.

The blades or valves 18 are formed of a length to correspond with thedistance between the ribs formed in the carriers 11 and 12 and providedwith the trunnions 16 and 16*, which trunnions are formed by cutting theends of the blade or valves 18 and then bending or rolling the cutportion, so as to I form trunnions, such as 16 and 16.

For the purpose of providing an arm to operate the blades or valves 18 aportion of the metal is cu to form said arms and then bent at an angle,thereby forming the arm 19.

The trunnion 16 is preferably formed by cutting loose the portion 20from one side of the center of the blade or valve 18, as shown in Fig.3, and then rolling or forming said out portion into the position shownin Fig. 6, by which arrangement the arm 19 is brought closest possibleto the trunnion 16.

It will be understood that the center grooving, fluting, or corrugations45, formed in the blades or valves 18, may be varied without departingfrom the nature of our invention.

The blades or valves 18 are provided upon their longitudinal edges withthe crimps, grooves, or curved flanges 21 and 22, which grooves, crimps,or flanges are for the purpose of adding strength to the blades orvalves.

In adjusting the valves or blades 18 they are so located and arrangedthat the grooves, cri-mps, or flanges 21 and 22 will overlap each other,as illustrated in the dotted lines, Fig. 1, and when said blades orvalves are brought into the position illustrated in the dotted lines theregister proper is closed or out 01%.

It will be understood that the grooves, crirn-ps, or flanges 21 and 22are to be formed .in opposite directions upon opposite longitudinaledges, allowing the edges of the blades or valves to overlap each other,thus preventing the passage of air and dust between the blades or valveswhen the register proper is closed.

It will be understood that in the arranging of the blades or valves, andinasmuch as all of the blades or valves must move in unison, the outeredges of the outer valves will come upon opposite sides of the flanges23 and 24, formed upon the side members 2 and 3, and for the purpose ofpreventing the passage of air and dust the flange 23 should be locatedsomewhat higher than the flange 24:, inasmuch as the outer edge of oneof the outer blades or valves mustcome under or engage the flange 23 andthe outer edge of the outer blade or valve must come on top or engagethe flange 24.

For the purpose of operating the blades or valves 18 the connecting-bar25 is provided. which connecting-bar is pivotally connected to the arms19 and to the operating-segment 26, said operating-segment beingpivotally connected to the blade or valve carrier 11 by means of therivet 27 or its equivalent.

It will be understood that when the operating-segment-26 is turned inone direction it will open the blades or valves 18 and when turned inthe opposite direction it will close the blades orvalves, said blades orvalves being opened and closed by the intermediate connection betweenthe segmen t for said blade or valve.

For the purpose of providing proper tension to the operating-segment 26the spring 28 is provided, which spring is located between the carrier11 andthe inner face of the operating-segmen t 26 and is held in placeby means of the rivet 27, which passes through the aperture 29, formedin said spring.

For the purpose of providing proper pivotalconnection between theoperating-segment 26 and the blades or valves 18 the operating-bar 25 isprovided with the pintles 30 and 31, which pintles may be struck fromthe operating-bar 25, as illustrated in Fig. 10. It will, however, beunderstood that said pintles may be formed in any well-known manner,inasmuch as our only object is to provide the pivotal connection betweenthe operating-segment and the blades or valves 18.

The box or frame proper is connected to the register-face 1 by means ofthe screws 32, and for the purpose of providing a sufficient amount ofmetal for holding the screws the flanges 8 are formed of two thicknessesof metal, thereby producing sufficient thickness of metal to formscrew-threaded apertures of sufficient strength to securely hold theregister-frame to the face 1.

It will be understood that by locating the blade or valve carrier 11 and12 as illustrated in the drawings the top flanges 7 of side members 2and 3 and top of flanges 13 of blade or valve carriers will form a levelseat for face 1 when the register is assembled.

Another object in constructing the blade or valve carriers as shown isthat they admit of the most rapid and easiest assembling of the parts11, 12, 18,and 25. As the blades or valves are placed in properposition, the connecting-bar is placed in its proper relation to engagethe arms 19, the trunnions are inserted in holes 15, and all of theabove parts as described lowered into the box or frame. The face 1 isplaced on top of boX, and screws 32 are inserted in holes in face 1.through holes 2* in parts 11 and 12 and into threaded apertures 3 in endmembers 4.

All of the different members of which this register is formed except therivets, screws, and operating-segment are constructed from sheet metalby blanking, punching, and forming the parts into proper shapes bysuitable means, producing registers of great durability,of lightestWeight, and lowest cost, and the breakage in shipping andfreight-charges are reduced to a minimum.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is-

1. In a hot-air and ventilating register, the combination of theregister-plate 1 having connected thereto the box or frame consisting ofthe members 2, 3 and 4, said members connected together, the members 4provided at their top or upper edges with double-folded flanges andtheir lower edges provided with the U-shaped portion 9, carriers 11 and12 provided with ribs14 and flanges 17, blades or valves provided withtrunnions and means for operating the blades or valves, substantially asand for the purpose specified.

2. The combination of a register-plate,members 2, 3 and 4, the members 2and 3 provided with angular flanges 5 and the flanges 7 located at theirupper edges, the members 4 having their ends located under the flanges7, the carriers 11 and 12 provided with flanges 13 located over flanges8, and said flanges located between the flanges 7 and means forfastening the lower edges of the parts 4 and 11, substantially as andfor the purpose specifled.

3. The combination of the end members 4 provided with the flanges 8formed of a double thickness of metal and the flanges located at anangle to said end members, the blade or valve carriers 11 and 12provided with flanges 13 and the flanges 13 located over thedoublefolded flanges 8, and a register-plate and means for connectingthe register-plate to the rectangular frame and means for connecting theparts 4 and 11 together, substantially as and for the purpose specified.
